Abstract:
    We present a study of the column density distribution and cosmological
    mass density of neutral gas from a survey of Damped Lyman-alpha
    systems in the Sloan Digital Sky Survey III Data Release 9.

Description:
    Our sample of high redshift Damped Lyman-alpha systems (DLAs) and
    sub-DLAs is presented along with associated metal equivalent widths
    and/or upper-limits.
